Sen. Mark Warner has a simple message to critics who say his Russia probe is in shambles: It just isn’t so.The top Democrat on the Senate Intelligence Committee said in an interview Tuesday that he always wants to move faster in investigating Russian interference in the 2016 election. But real progress is taking place, he said, including on scrutiny of ties between Moscow and President Donald Trump’s aides.“People who think we're not looking at that now have not received an update,” Warner told POLITICO.The Virginia Democrat rejected criticism over the fact that the panel has yet to issue subpoenas or interview high-profile witnesses like former Trump advisers Roger Stone, Carter Page and Michael Flynn.
